Well with the new hard drive in it allowed the pc to turn on and stay on. Unfortunately we couldn't get the rescue disc they supplied to work.
She phoned them the following day, demanding that they sent someone out (as it said they would in the mastercare policy). They put her on hold and then put the phone down on her. She's not a very happy person to say the least. Will post updates as and when I get them. This could be interesting.
